SELF-SUPPORTING COMBINATION-PAVEM ENT.

SPECIFICATION forming part of Letters Patent No. 347,557. dated August 17, 1886.

AApplication tiled March 25, 1886. Serial No. 196,590. (No model.)

v ing is a specification.

My invention relates to such pavements which not only serve as such, but also as a cover or ceiling for parts of the cellars where they extend out under the pavement, as is very often the case.

AThe object of my invention is to provide a cheap, light, and durable pavement so c onstructed as to allow of the employment of a large variety of ornamental patterns for the upperror walking surface. I attain these objects by the construction described in the following specication and illustrated in. the accompanying drawings, in which- VFigure 1 is a side view of my pavement in position, showing the supporting-walls in section. Fig. 2 is a top view of a section of the pavement.V Fig. 3 is an under side view of the same. Fig. 4 shows at an enlarged scale a cross-sectionlof the pavement, looking toward the gutter.

A vis a rectangular ilat casting, having an upturned ilange, a, of even height all round. The space between said flange may be divided by any number of cross-ribs a', suitably arranged so as to present a symmetrical appearance when a large number of the sections are laid side by side. On the under side of said casting, at each end of it, are two iiat bearingsurfaces, b b', by which -the section rests on its supporting-walls, of which C is the main wall of the building, and D the outer wall, which does not rise above the surface of the street.

Portion c of Awall C represents the cellarwall, and, being thicker than the Wall above the pavement, forms an offset, on which the upper or higher end-of the latter rests. Those iiat bearing-surfaces b b are so arranged that they rest horizontally or level on their supports, while the section itself is slightly inclining toward the gutter. Between those bearing or resting surfaces any suitable number of strengthening and supporting ribs, f, may traverse the underside of the casting longitudinally.

To the outer and lower end of the pavement the gutter L is attached, and may either be an integral part thereof or bolted or otherwise secured thereto. The iron next extends downwardly to sufficient depth, as shown at el, and then is bentout and upwardly, as shown at d, so as to shape the gutter, to the outer edge of which the pavement M of the street joins. Strengthening-ribs g are also provided below, one of which, g', runs crosswise at the extreme edge of the gutter, so as to provide au abutment for thepaving-stones of the street,

to prevent their slipping under the gutter on I opening their joints. The divisions on the upper surface between the ribs a a are filled in to a level with said ribs and flanges a with cement or any other suitable Well-wearing substance, as shown in Figs. 2 and 4.

Apavement of this sort presents an elegant appearance, and is not very costly. It is also easily kept in repair, as any section or divis- -ion may be repaired by itself. The different arrangement and number of the divisional ribs a a admit the useV of many-different designs and patterns, which variety may be still increased by filling the adjoining divisions with differently-colored cement, as shown in Fig. 2, where the lined divisions are intended to indicate different colors.

`I am aware that similar constructions have been used for similar purposes, and therefore I do not claim the combination of iron and cement, broadly; but

What I do claim, and want-to secure by Letters Patent, is as follows:

1. In a combined pavement-section and cellar-cover supported at its two eXtreme ends only, the combination, asdescribed, of cast-iron body A, having ornamental ribs a',

being filled in with cement or similar Inaterial, and marginal flange a, to hold said llin'g material and keep it from breaking out, the non-supported portions of the frame being provided with strengthening-mbsf below, and having bearing-surfaces b b', so constructed as to be horizontal and lie level on theirsupports, one being so much lower as to give the pavement-section the proper inclination one way toward the gutter.

2. In a pavement-section, thecombination of a cast-iron body, A, having a marginal ICO In testimony of which invention I hereunto set my hand.
